Abstract

OBJECTIVE:

To determine the effects of maternal gestational diabetes mellitus (GDM) on offspring adiposity in a well-characterized cohort of Mexican American mother-child pairs.

STUDY DESIGN:

This study included 62 Mexican American mothers and their index offspring. Maternal GDM and normal glucose status during index pregnancy were documented, and mothers were previously matched by age, body mass index (BMI), and parity. Mother-child pairs were recruited when offspring were between the ages of 5 and 16 years. A medical history was collected, and anthropometrics were measured. Main outcome measures were offspring BMI, BMI z-scores, BMI percentiles, and hip and waist circumferences.

CONCLUSION:

Intrauterine exposure to GDM is associated with greater adiposity in Mexican American children, and this relationship is not mediated by maternal obesity. In contrast to previous reports, this study included only Mexican Americans; thus, ethnic variations may influence the contributions of maternal GDM and maternal obesity to offspring adiposity.
